Where is the central ray directed on the plantodorsal axial?
 
 mid calcaneus
  base of the 3rd metatarsal
  mid metatarsals
  tuberosity of the calcaneus

Question 2

Application of technique charts should be considered primarily:
 
 for reproducibility
  to extend the life of the x-ray tube
  to improve department efficiency
  to help minimize patient dose

Answer to Question 1

base of the 3rd metatarsal

Rationale: The central ray is directed to the base of the third metatarsal on the plantar surface of the foot. This centering and the tube angle should direct the beam through the talocalcaneal joint.

Answer to Question 2

to help minimize patient dose

Rationale: Technique charts help guide technologists in technical factor selection. They are used to try to reduce the need for repeat images.
